Jason is correct. The IQ system uses line to line PLC, whereas the M-Series microinverter communications were line to neutral. Most of the noisy loads (like magnetic ballasts, touch lamps, etc) are 120V line to neutral loads. For that reason, we see very
few communication issues with the IQ microinverters.</div>

Also, the widespread adoption of combiner boxes has had a huge effect on improving communications.

@scot.arey@solarcentex.com</a>, can you confirm that this site is using a combiner box. Keeping the microinverter and Envoy circuits separate from the other house loads is critical to ensuring good communications. We also have a power line filter product
(Q-LCF-064-1P) that can be installed between the combiner and the main panel in the rare instances there are poor comms. That filter is very robust and has been designed to filter noise and signals in the 110kHz IQ microinverter communication frequency.</div>
